The TASKMASTER ROVER’s twin-shaft grinder slowly travels in close proximity to the inside of a curved stainless steel screen. Solids captured on the screen are swept by the grinder and aggressively reduced by two banks of counter-rotating intermeshing cutters. The discharged solids either pass through the screen or are automatically cycled back through the grinder for further reduction. This design provides unique control of the output for a fully processed, homogenous liquid flow. There are no corners, crevices, sudden changes or blockages to interfere with the flow. With its large open area, the ROVER is practically invisible to the liquid flow. The ROVER handles flow rates up to an incredible 54 mgd (7450 m3/hr).
